Choosing a pharmacy and a pharmacist is important. You should find a pharmacy where you feel welcome and where the staff explains things well.
Remember that pharmacists are an important member of the healthcare team. When they prepare your medicines, they check your history and allergies, look for possible interactions, and contact your prescriber if they have any questions about the appropriateness of the medicine. When you use the same pharmacy for all your medicines, it will be easier for your pharmacist to know about your medicine history and changes in your prescribed medicines.
Be careful if you use an online pharmacy. About half of the medicines bought from websites that hide their addresses are counterfeit (fake).
